Abstract

Improvements introduced in the object of the main patent no. 367,524 by "a procedure for the preparation of an optically active tiadiazol", consisting of heating a reaction mixture containing s-5- (3-morpholino-1,2,5-thiadiazole 4-oxymethyl) -3-tert-butyloxazolidin-2-one, a catalytic amount of dibutyltin oxide, sulfate or acetate and benzyl alcohol, followed by heating the resulting residue in a concentrated mineral acid to obtain s-3-morpholino- 4- (3-tert-butylamino-2-hydroxypropoxy) -1,2,5-thiadiazole.
